FILE - In this March 21, 2018 file photo, Jim Parsons, a cast member in the television series "The Big Bang Theory," poses during the 35th Annual PaleyFest at the Dolby Theatre in Los Angeles. An injury to actor Parsons has forced the cancellation of a performance of the Broadway revival of "The Boys in the Band." People who said they attended the Saturday, May 12, 2018, matinee performance indicated on Twitter that Parsons tripped during the encore and limped off while other cast members took their bows.
